- - Excessively used pesticides and fertilizers seep into the soil and groundwater.
- - Fossil-fuel power plants emit greenhouse gases, carbon dioxide and sulfur compounds that cause acid rain. For this reason it is necessary to equip power plants with filtration devices and efficient environmental management systems. Chemical industry, crude oil processing and metallurgical industry are also sources of industrial waste.
- - In animal husbandry, methane is released into the air, which is a greenhouse gas. Excessively used pesticides and fertilizers also cause air pollution.
- - The nutrient levels of waters may increase due to fertilizers, causing eutrophication. Because of this phenomenon a growth of algae and mosses may be observed in still waters.
